证明了不含交叉项干扰且具有Wigner Ville分布 (WVD)聚集性的时频分布是不存在的 ,并且不含交叉项干扰而聚集性充分接近WVD聚集性的时频分布一般也不存在 .
It is proved that there is no time-frequency distribution without the cross-term interference and with the WVD gather, and the time-frequency distribution that does not contain crosstalk and whose aggregation is close to WVD aggregation generally does not exist.
